Abstract

The combination of different rock properties will make different effects of the Deformation and Failure in Overlying strata, this paper uses the ADINA finite element software to establish two-dimensional model to simulate analysis the four kinds of different overburden structures displacement field variation characteristics in the conditions of seepage and mining. The results show that when mining is completed, the surface of overlying strata structure were formed a completely symmetrical subsidence basin and antisymmetric horizontal movement curve, The sinking value of open-off cut and the working face is above the inflection point is half of the maximum subsidence, the curve slope from the boundary to the inflection point increases gradually, the curve slope from the inflection point to the center point becomes smaller. The maximum displacements due to overlying lithology vary, the surface maximum settlement value is 3.80M and the minimum settlement value is 2.34m. The floor heave has little difference, the maximum value and the minimum value is only 0.17mm.
